Assigned PDF / FPL
Magnetic azimuth of machine gun to prominent terrain feature
Dead space
Areas signifying grazing fires
Specified targets numbered in sequence w/ direction in mild
Rough sketch/ drawing serves as record of firing data & document for defensive fire planning.
One copy remains at gun position as record of firing data
Gunner uses card to recall data to fire on predetermined targets & as aid in estimating ranges to other targets during good visibility.
Other copy is sent to next higher hq, who use it to organize defense & prepare fire plan sketch
Integration of weapons system on fire plan
Machine guns have capabilities & limitations just as any weapon system does.
Though powerful weapons do not stand alone.
Most effective employed in concert w/ other weapons in attempt to achieve synergetic effect where fires of 1 weapon compliment & augment fires of another.
Capabilities & limitations of every available weapon must be considered in order to achieve this in tactical plan.

Grazing fire (respect to ground)
Fire appox parallel to ground where center of cone o fire does not rise above 1 meter
Plunging fire (respect to ground)
Fire in which angle of fall of rounds w/ reference to slope of ground is such that danger space is practically confined to beaten zone & length of beaten zone is materially shortened.
Frontal (respect to target)
Long axis of beaten zone is at right angle to long axis of target
Flanking ( respect to target)
Delivered against flank of target
Oblique fire (respect to target)
Long axis of beaten zone is at angle, but not right angle, to long axis of target
Enfilade fire (respect to target)
Long axis of beaten coincides w/ long axis of target. Either frontal/flanking & is most desirable class of fire w/ respect to target because it makes use of max beaten zone.
Classes of fire w/ respect to gun
